Background: Colorectal cancer (CRC) is a major cause of cancer deaths globally, mainly due to treatment resistance. Neddylation, a key post-translational modification, is linked to tumor growth and immune response, offering potential therapeutic targets, though its role in CRC is not well-explored.

Methods: We examined neddylation-related genes (NRGs) across cell subtypes using CRC scRNA-seq data from the TISCH database.

This study aimed to isolate lactic acid bacteria from monkey faeces and evaluate their safety and probiotic properties through a combination of in vitro assays and complete genomic sequencing. The results revealed that two strains (LDHa and LSHe) exhibited promising probiotic attributes: no hemolytic activity, remarkable antibacterial activity against intestinal pathogens, high bile salt tolerance (77.46% survival rate for LDHa at 0.

Pancreatic cancer (PC) is a highly malignant digestive system tumor with poor prognosis, and cancer stem cell (CSC) is known to drive its progression, metastasis, and recurrence. The transforming growth factor-β (TGF-β)/small mothers against decapentaplegic 3 (Smad3) signaling is implicated in various cancers, yet its role in PC remains underexplored. This study aimed to investigate the involvement of the TGF-β/Smad3 pathway in PC development and stem cell-like properties by examining its regulatory effects on PC cells.

Bladder cancer (BLCA) exhibits profound chemoresistance, partly mediated by metabolic dysregulation. This study investigated the roles of phenylalanine (Phe) and cholesterol metabolism in BLCA chemoresistance using integrated omics and computational modeling. Transcriptomic analysis of the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets revealed that elevated hexokinase 2 (HK2) and low-density lipoprotein receptor (LDLR) expression correlates with poor response to cisplatin.

Background: Avian bornavirus (ABV) is a neurotropic virus, it has been established as the primary causative agent of proventricular dilatation disease (PDD). However, substantial international trade and transnational trafficking of wild birds occur, potentially enabling these birds to harbor and transmit pathogens to domestic poultry, adversely affecting their well-being. Real-time RT-PCR was employed to detect the presence of PaBV-4 in parrots imported to China in 2022.

Claudins (CLDN) are structural components of tight junctions that function in paracellular transport and maintain the epithelial barrier function. Altered expression and distribution of members of the claudin family have been implicated in several cancers including breast cancer (BC). We performed a comprehensive analysis of the expression and prognostic value of claudins in BC using various online databases.

Immunotherapy is an effective treatment for many cancer types. However, YTHDF2 effects on the prognosis of different tumors and correlation with tumor immune infiltration are unclear. Here, we analyzed The Cancer Genome Atlas and Gene Expression Omnibus data obtained through various web-based platforms.

Introduction: Diabetes mellitus (DM) patients suffer from high morbidity and premature mortality due to various diabetic complications and even cancers. Therefore, this study aimed to identify key genes involved in the pathogenesis of diabetic peripheral neuropathy (DPN) and pancreatic cancer (PC).

Methods: We analyzed three gene expression profiles (GSE95849, GSE28735 and GSE59953) to obtain differentially expressed genes (DEGs).

Background: This study was performed to identify genes related to acquired trastuzumab resistance in gastric cancer (GC) and to analyze their prognostic value.

Methods: The gene expression profile GSE77346 was downloaded from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were obtained by using GEO2R.

Background: This study was performed to identify disease-related genes and analyze prognostic values in nonsmoking females with non-small cell lung carcinoma (NSCLC).

Materials And Methods: Gene expression profile GSE19804 was downloaded from the Gene Expression Omnibus (GEO) database and analyzed by using GEO2R. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes were used for the functional and pathway enrichment analysis.

The controversy of (p53) in nasopharyngeal carcinoma persists, despite the fact that many studies have been conducted on its correlation with latent membrane protein 1 (LMP1), bcl-2, and prognosis. To better understand this postulated relationship, a meta-analysis was performed based on existing relevant studies. A total of 19 individual studies with a total of 1189 patients were included in the meta-analysis.

Sparganosis is a zoonotic disease caused by the spargana of Spirometra, and snake is one of the important intermediate hosts of spargana. In some areas of China, snake is regarded as popular delicious food, and such a food habit potentially increases the prevalence of human sparganosis. To understand the prevalence of Spirometra in snakes in food markets, we conducted a study in two representative cities (Guangzhou and Shenzhen), during January-August 2013.

Aptamers are single-stranded nucleic acid molecules that can be used for protein recognition, detection, and inhibition. Over the past decades, two thrombin-binding aptamers (15apt and 27apt) were reported by systemic evolution of ligands by exponential enrichment technique. Though many studies have been reported about the interactions between the aptamers and thrombin by atomic force microscopy, the thrombins in those studies were all immobilized by chemical agents.

Emerging evidence confirms that cancer stem cells (CSCs) are responsible for the chemoradioresistance of malignancies. EBV-encoded latent membrane protein 1 (LMP1) is associated with tumor relapse and poor prognosis of nasopharyngeal carcinoma (NPC). However, whether LMP1 induces the development of CSCs and the mechanism by which this rare cell subpopulation leads to radioresistance in NPC remain unclear.

Approximately 30% of patients with Epstein-Barr virus (EBV)-positive advanced nasopharyngeal carcinoma (NPC) display chemoresistance to cisplatin-based regimens, but the underlying mechanisms are unclear. The Epstein-Barr virus (EBV)-encoded latent membrane protein 1 (LMP1), a functional homologue of the tumor necrosis factor receptor family, contributes substantially to the oncogenic potential of EBV through the activation of multiple signaling pathways, and it is closely associated with a poorer prognosis for NPC. Recent studies show that EBV infection can induce the expression of many cellular miRNAs, including microRNA-21, a biomarker for chemoresistance.

Background: Epstein-Barr virus (EBV) is an etiological cause of many human lymphocytic and epithelial malignancies. EBV expresses different genes that are associated with three latency types. To date, as many as 44 EBV-encoded miRNA species have been found, but their comprehensive profiles in the three types of latent infection that are associated with various types of tumors are not well documented.
